Could I be pregnant???? Please help!?

I never had a regular period until I started dating my boyfriend on September 26th 2010, and since then I had my period on the 26 every month! Then in march I got it a day late, then April went back to the 26th, and then in may started on the 28th. It is now June 29th and I have still yet to start. My boyfriend and I use a condom EVERY time! And what's really confusing me is that I'm getting all te normal symptoms I get before I start my period! My breasts are tender and bigger like they usually get, I'm getting off and on cramping, and I'm definitely PMSing haha I'm starting to get really scared.. I don't know if it's even to early to take a pregnancy test or not and I'm just starting to freak out. Someone help please?
